Looks nice, but rusted after 6 months of use
Color: Black
The caddy was aesthetically pleasing, with enough room to hold my dish soap, hand-soap and sponge as well as a brush. I really love how it looks, but only after 6 months of using this, the wires in the holder is already rusted. It looks nice but not really of good quality.

Love that it drains into the sink!
Color: Black, Color: Black
Loving it so far! I put water in it to show how it drains into the sink. But when the water that comes off of the scrub brushes and sponges from regular usage, it does drain like it’s supposed too. There is some water that sits there but for the most part, it does drain into the sink. The little bit of water that sits there, ends up evaporating. It fits the 26 fl. Oz. Of dish soap, which is great! It holds the sponges in place. Helps to keep things around the sink clean. I had another storage container that held my stuff in but it didn’t drain into the sink so mold would form and I would have to throw stuff away. I like the fact this one has a drain, so that water doesn’t stand on the bottom and create mold after awhile. It’s easy to assemble. The quality is great! It’s easy to clean!// 8/23/25 love it so much, I bought a 2nd one for the other side of my sink! It’s also easy to clean as well.

Great sink caddy!
Color: White
This sink organizer is simple yet allows variable ways to accommodate storage. It has plenty of space to store a large bottle of dish soap in addition to sponges, brushes, and scrub pads. I choose the white design which complements my white cabinets perfectly!
